aggregation operators (aos) have been studied by many schol- ars. as many aos are proposed, there is still lacking approach to classify the categories of ao, and to select the appropriate ao within the ao candidates. in this research, each ao can be regarded as a cognitive style or individual dierence. a cognitive style and aggregation operator (csao) model is pro- posed to analyze the mapping ...

In this contribution the way algorithms for object detection in urban areas are integrated into the knowledge-based image interpretation system GeoAIDA is described. Generic scene models are used for object detection in settlement areas, whereas the implementation of the respective algorithms is a collection of stand-alone-operators. With GeoAIDA a system is available which uses these operators...

1. Basic facts from the spectral theory of magnetic quantum Hamilto-nians (Schrödinger, Pauli, and Dirac operators with magnetic fields): self-adjointness, gauge invariance, diamagnetic inequality, Aharonov-Casher theorem [1, 7]. Constant magnetic fields [1]. 2. Berezin-Toeplitz operators and pseudodifferential operators with con-4. Resonances for the 3D Schrödinger operator with constant magne...

Shape-from-focus (SFF) has widely been studied in computer vision as a passive depth recovery and 3D reconstruction method. One of the main stages in SFF is the computation of the focus level for every pixel of an image by means of a focus measure operator. In this work, a methodology to compare the performance of different focus measure operators for shape-from-focus is presented and applied. ...

Vanclay, J.K., 1991. Aggregating tree species to develop diameter increment equations for tropical rainforests. For. Ecol. Manage., 42: 143-168. Pairwise F-tests provided an efficient approach for aggregating large numbers of species into a manageable number of groups for developing diameter increment functions. The first stage of the two-stage procedure identified the number of groups required...

In the study, we propose the Associated Probability Intuitionistic Fuzzy Weighted Averaging (As-P-IFWA) and the Associated Probability Intuitionistic Fuzzy Weighted Geometric (As-P-IFWG) aggregation operators with associated probabilities of a fuzzy measure presenting an uncertainty. Decision makers' evaluations are given as intuitionistic fuzzy values and are used as the arguments of the aggre...

neural networks solving approximation problem. It is based on two hierarchical evolutionary algorithms with multiobjective Pareto optimisation. The lower level algorithm searches for rules that are optimised by the upper level algorithm. The conclusion of the rule takes the form of a tree whose inner nodes contain functions and operators, and leaves—identifiers of attributes and numeric constan...

This paper examines the opportunities existing within the multidimensional database (MDDB) approach to support spatio-temporal data exploration and analysis (STEA). MDDB-specific technology used for Data Warehousing and On-Line Analytical Processing (OLAP) is recognized for supporting easy query building, rapid query run times and simple interactive navigation within multiple displays, includin...

We prove a new representation of the generator of a subordinate semigroup as limit of bounded operators. Our construction yields, in particular, a characterization of the domain of the generator. The generator of a subordinate semigroup can be viewed as a function of the generator of the original semigroup. For a large class these functions we show that operations at the level of functions has ...

q-vertex operators for quantum affine algebras have played important role in the theory of solvable lattice models and the quantum KnizhnikZamolodchikov equation. Explicit constructions of these vertex operators for most level one modules are known for classical types except for type C (1) n , where the level −1/2 have been constructed. In this paper we survey these results for the quantum affi...
